The level of sugars content in sweet cherry fruit depends on many factors. However,
the decisive influence of weather factors is noted. In view of this, the issue of predicting the sugars
content in sweet cherry fruit depending on the share of weather factors is relevant for further
improvement of transportation technology, storage and processing.
It has been established that according to sugars content and to the variability of their formation
the most perspective from the technological point of view were varieties: Zabuta (12.47%),
Dachnytsia (15.60%), Krupnoplidna (14.35%). Low and medium variabilities of the selected
varieties according to the investigation years were established (VΡ = 8.6%β13.0%). It has been
shown that weather conditions had dominating effects on sugars accumulation for all varieties
groups irrespective of the ripening period. According to the results of a two-factors dispersion
analysis it is expedient to prognosticate the sugars content in sweet cherry fruits by medium
values for a particular group of sorts but not for each pomological sort.
In the course of the work the average and strong correlation dependence between 14 weather
factors (Π₯Ρ, i = 1..14) and the sugars content for sweet cherries of early, medium, and late ripening
period (|πππππ
| β₯ 0.55, π = 1. .14, π = 1. .3) were defined. The ranges of share of weather factors
participation that have the maximum influence on sugars fund formation in sweet cherry fruit are
established (βπ 9.50% to 30.99%) .
Based on regression analysis, it is substantiated that the sugars accumulation in sweet cherry fruit,
regardless of the ripening period, is most influenced by weather conditions of the blossoming
period, the last month of fruit formation and thermal parameters and humidity index at the stage
of fruit picking.
